APPARATUS FOR LIGH TING STREETS, 80C.

SPECIFICATION formingpart of Letters Patent No. 292,127, datei January15, 1884,

Application filed August .35, 1883. (N0 model.)

To all whom it may concern:

Be it known that I, BARNARD W. MITCH- ELL, of Hubbard, in the county ofTrumbull and State of Ohio, have invented certain new and usefulImprovements in Apparatus for Lighting'Streets; and I do hereby declarethat the following is a full, clear, and exact description of theinvention, which will enable others skilled in the art to which itappertains to make and use the same, reference being had to theaccompanying drawings, which form a part of this specification, and inwhich Figure 1 is a view of the entire apparatus, and Fig. 2 is avertical section of one of the lamp-posts.

Similar letters of reference indicate corresponding parts in both thefigures.

My invention has relation to that class of apparatus for lightingstreets in which oil is forced from a reservoir through pipes intotubular lamp-posts provided with wicks and burners; and the novelty ofmy improvement consists in the combination of the tubular lamp-posts,perforated wick-tubes, stop-cocks, and oil-mains, as will be hereinaftermore fully described, and particularly pointed out in the claim.

In the accompanyingdrawings, the letter A indicates a reservoir or tanksupported upon pillars B,having a closed aperture, 0, through which itmay be filled, and having a gage, D, through which the height of the oilmay be ascertained. One of the supporting-pillars is hollow, openinginto the tank, and is provided with a stop-cock, H, and is continuedinto the main E, through which the oil is distributed to the severallamp posts, F. These posts are tubular, open with their lower ends Yinto the main, at which points they are provided with stop-cocksG, andare provided with lanterns G at their upper ends. The stop-cocks have: alever or handle, I, secured at a right angle to the plug to the end ofthe same, and may be turned by means of con necting-rods J, forminghandles K at their upper ends, which handles are removably secured tolugs L,projecting from thelamp-posts,

by means of padlocks M or similar looks, so that the cooks cannot beturned excepting by a person having the key for thelock. Inside thelamp-post is a perforated tube, N, inside which the wick 0 passes, thesaid tube extending 'from the top to the bottom of the post, down to thestop-cock G, which is inserted transversely through the post, I and withthe opening in which it registers, and this tube supports the wick andprevents it from being raised by the flow of oilin the post, which mightcause a stoppage in the post, as well as it prevents too heavy a strainupon the burn 6o er and wick-raising mechanism, which would cause aconsiderable strain on the burner and the raising mechanism by theweight of the same, if the wick is allowed to hang down free, while theperforations allow free access 65. of the oil to the wick. I It will beseen that the flow of oil may be regulated or stopped for each separatepost, as well as for all the posts, by means of the individualstop-cocks or the general stop-cock at the reservoir, and that themechanism operating the individual cocks is so simple as to not easilyget out of order, being at the same time very efficient. I

I am aware that it is not new to supply street-lamps with oil carriedthrough pipes from a tank or reservoir, an'dI do not wish to claim suchconstruction, broadly; but

What I claim, and desire to secure by Letters Patent of the UnitedStates, is- A The combination of the tubularlamp-posts, the perforatedwick-tubes extending from the burner down to the stop-cock, thestop-cock inserted transversely through the tubular post at the lowerend of the perforated wicktube, with its opening registering with saidtube, means for opening and closing said stopcock, and the main feedingthe oil to the posts from a common reservoir.

BARNARD \V. MITCHELL.
